Abstract
A switch construction comprises a waterproof housing and first and second contact assemblies in the housing which are operative for effecting and interrupting electrical continuity in first and second lines, respectively, of an electrical circuit connected to the switch. The switch is operable by manually depressing a rubberized cover on the housing to effect continuity in the first and second contact assemblies; and when pressure is released from the cover, the contact assemblies are resiliently returned to their original positions and continuity is interrupted in the switch.
Claims9
A switch construction comprising:
- a. a housing;
- b. a first contact assembly in said housing comprising;
- i. a fixed contact electrically connected to a first terminal on the exterior of said housing;
- and
- ii. a resiliently movable stressed contact member electrically connected to a second terminal on the exterior of said housing and movable with a snap action between a first position wherein it is spaced from said fixed contact and a second position wherein it is in engagement therewith;
- and
- c. a second contact assembly in said housing comprising:
- i. a resiliently movable actuator contact member electrically connected to a third terminal on the exterior of said housing and electrically insulated from said stressed contact member but depressible to move said stressed contact member from said first position thereof to said second position thereof;
- and
- ii. a first resilient blade member electrically connected to a fourth terminal on the exterior of said housing and engageable with said actuator contact member to first electrically interconnect said third and fourth terminals and to then depress said actuator contact member to thereby move said stressed contact member to said second position thereof.
