Claims
- 1. A delay switch comprising:an operating section; and a delay unit including: a suction cup linked with said operating section; a slidable T-post that is distinct from said operating section, said slidable T-post being slidably abutable to said operating section, and said slidable T-post cooperating with said suction cup and said operating section to open and close a switching mechanism; a body to hold said suction cup with a holding force; a return spring having a spring force urging said suction cup in a direction separating said suction cup from said body; and a terminal with which the switching mechanism is electrically connected, wherein said delay unit produces a delay time, said delay time beginning when said spring force of said return spring urges said suction cup in said direction, said delay time concluding when said holding force of said suction cup to said body is overcome by said spring force of said return spring; and wherein said delay unit includes a case in which at least said suction cup and said body are accommodated; and wherein said delay unit further includes a dust protection member movable with said slidable T-post and which separates said suction cup from an inside surface of said case.
- 2. A delay switch according to claim 1, wherein said dust protection member includes an elastic suction cup cover accommodated in said case and linked with said slidable T-post.
- 3. A delay switch according to claim 1, wherein said body is made of a porous material.
- 4. A delay switch according to claim 1, wherein said slidable T-post is defined by a slidable T-post member to open and close said switch mechanism and a drive shaft member to hold said suction cup, and said slidable T-post member is integral to said drive shaft member.
- 5. A delay switch according to claim 1, wherein said slidable T-post is defined by a slidable T-post member to open and close said switch mechanism and a drive shaft member to hold said suction cup.
- 6. A delay unit being operatively combined with an operating section, said delay unit comprising:a suction cup; a slidable T-post that is distinct from said operating section, said slidable T-post being slidably abutable to said operating section, and said slidable T-post cooperating with said suction cup and said operating section; a body holding said suction cup with a holding force; a return spring having a spring force urging said suction cup in a direction separating said suction cup from said body; a case accommodating at least said suction cup and said body, wherein said delay unit produces a predetermined delay time beginning when said spring force of said return spring urges said suction cup in said direction, said delay time concluding when said holding force of the suction cup to said body is overcome by said spring force of said return spring; and wherein said delay unit includes a dust protection member movable with said slidable T-post and which separates said suction cup from an inside surface of said case.
- 7. A delay switch according to claim 6, wherein said dust protection member includes an elastic suction cup cover accommodated in the case and linked with the slidable T-post.
- 8. A delay switch according to claim 6, wherein the body is made of a porous material.
- 9. A delay switch according to claim 6, wherein said slidable T-post is defined by a slidable T-post member and a drive shaft member to hold said suction cup, and said slidable T-post member is integral to said drive shaft member.
- 10. A delay switch according to claim 6, wherein the slidable T-post is defined by a slidable T-post member and a drive shaft member to hold said suction cup.
- 11. A delay device comprising:a main body extending in a longitudinal direction, said main body including a delay unit accommodating section with ends aligned in said longitudinal direction, said main body further including terminal accommodating sections provided adjacent to said ends; an operating unit including a cover member mounted onto said main body, said cover member having an opening and a handle mounted in said opening; a delay unit located in said delay unit accommodating section, said delay unit including: a suction cup; a slidable T-post that is distinct from said operating unit, said slidable T-post being slidably abutable to said operating unit, and said slidable T-post cooperating with said suction cup and said operating unit; a body holding said suction cup with a holding force; a return spring having a spring force urging said suction cup in a direction separating said suction cup from said body; and a case accommodating at least said suction cup and said body; and a switch mechanism cooperating with said operating unit and said delay unit, said delay unit producing a predetermined delay time beginning when said spring force of said return spring urges said suction cup in said direction, said delay time concluding when said holding force of the suction cup to said body is overcome by said spring force of said return spring; and wherein said delay unit includes a dust protection member movable with said slidable T-post and which separates said suction cup from an inside surface of said case.
- 12. A delay switch according to claim 11, wherein said switch mechanism includes terminal plates, said terminal plates include a movable-contact side terminal plate and a first fixed terminal plate with a first fixed contactor, said movable-contact side terminal plate has a movable contactor with a first movable contactor contactable with said first fixed contactor, and wherein said movable-contact side terminal plate and said first fixed terminal plate are accommodated in said terminal accommodating sections, respectively.
- 13. A delay switch according to claim 12, wherein after said delay time is terminated, said first fixed contactor and said first movable contactor are separated.
- 14. A delay switch according to claim 12, wherein said terminal plates include a rocking member with a second movable contactor and a second fixed terminal plate with a second fixed contact contactable with said second movable contactor, and said second fixed terminal plate is accommodated in said terminal accommodating sections.
- 15. A delay switch as claimed in claim 14, wherein said second fixed contactor and said second movable contactor are separated at the beginning of said delay time.
- 16. A delay switch according to claim 11, wherein said dust protection member includes an elastic suction cup cover accommodated in the case and linked with the card.
- 17. A delay switch according to claim 11, wherein the body is made of a porous material.
- 18. A delay switch according to claim 11, wherein said slidable T-post is defined by a slidable T-post member to open and close said switch mechanism and a drive shaft member to hold said suction cup, and said slidable T-post member is integral to said drive shaft member.
- 19. A delay switch according to claim 11, wherein the slidable T-post is defined by a slidable T-post member to open and close said switch mechanism and a drive shaft member to hold said suction cup.
