Claims
- 1. A push-button switch, comprising: a switch mechanism;
- a switch base for supporting said switch mechanism;
- a switch cover mounted on said base and enclosing said switch mechanism, said switch cover having a cam mounted on the exterior thereof;
- a reciprocating plunger having an operating member, a lower end of said operating member engaging said switch mechanism to turn the switch on and off, said operating member having an opening formed therein for cooperation with said cam;
- a push button attached to said reciprocating plunger so that when said push button is depressed, the reciprocating plunger is reciprocated so that said operating member acts on the switch mechanism;
- a housing for sealingly enclosing said switch mechanism, switch base, switch cover, and reciprocating plunger;
- wherein said cam cooperates with said opening so that said cam locks the reciprocating plunger in either a first position, in which the switch mechanism is turned off, or a second position, in which the switch mechanism is turned on.
- 2. The push-button switch of claim 1, wherein an opening is formed on the housing and a pawl is formed on an elevated portion which extends above the switch base such that the housing and the switch base are coupled together by the engagement of the pawl and the opening.
- 3. The push-button switch of claim 1 further comprising:
- a pair of springs biased against the reciprocating plunger for returning the reciprocating plunger from the second position to the first position.
- 4. The push-button switch of claim 1 wherein the switch base is formed from a first part and a second part, with each part having a projection for inserting into the other part to thereby unite the two parts, and wherein the first part supports two terminals of a first type and the second part supports two terminals of a second type such that each terminal of the first type is associated with a terminal of the second type to thereby form two separate switch mechanisms.
- 5. The push-button switch of claim 1, wherein said switch mechanism comprises at least one fixed lower contact, at least one fixed upper contact, a movable member movable so that it contacts either said fixed lower or upper contact, an erected member, one end of which is connected to said movable member and another end of which engages said operating member, and a biasing spring attached to said erected member so as to bias said movable member against the fixed lower contact, and wherein said switch cover further comprises a regulating member which contacts said biasing spring in order to hold the biasing spring in place during assembly of the switch.
- 6. The push-button switch of claim 1, further comprising a light emitting element holder attached on top of said switch cover and a light emitting element disposed within said light emitting element holder, wherein said switch over has two terminal engagement grooves located on opposing outer surfaces thereof and said switch further comprises two light emitting terminals for engaging terminals of said light emitting element, said light emitting terminals being fitted in said terminal engagement grooves.
- 7. The push-button switch of claim 6, wherein said switch cover further comprises two terminal insertion portions in which both the terminals of said light emitting element and end portions of said light emitting terminals are inserted.
- 8. The push-button switch of claim 4, wherein said first and second part each further comprise a rising connection portion elevated above the switch base, the rising connection portions of said first and second part being connected together to further unite the two parts.
