Abstract:
1. A non-teasable switch, comprising: a first contact movable toward a second contact from a switch-deactuated position to a switch-actuated position and movable away from said second contact from said switch-actuated position back to said switch-deactuated position, said first contact releasably contacting said second contact in said switch-actuated position and said first contact being separated from said second contact in said switch-deactuated position; a transfer carriage operatively engaged with said first contact and being movable toward and away from said second contact between said switch-deactuated and switch-actuated positions, said transfer carriage including a flip-flop mechanism for bringing said first contact into contact with said second contact and for releasing said first contact from said second contact; said flip-flop mechanism overcoming a transfer barrier between said switch-actuated and switch-deactuated positions; and an actuator operatively engaged with said transfer carriage and being movable toward and away from said second contact, said actuator being movable so as to impart movement on said transfer carriage and said first contact between said switch-deactuated and switch-actuated positions, and said actuator being movable so as to impart movement on said transfer carriage to overcome said transfer barrier from both said switch-deactuated and switch-actuated positions; wherein, through said actuator and said transfer carriage, said first contact is transferred into and out of contact with said second contact, the non-teasable switch further comprising a lock device, said lock device being configured and arranged so as to lock said actuator and said transfer carriage in either of said switch-actuated or switch-deactuated position.
