ABSTRACT:
A crystal vibrator actuated relay device including a switch having a contact button displaceable between first and second positions, the switch being open at one of the positions and closed at the other of the positions. A first lever arm is coupled to the contact button and is displaceable with the contact button between first and second positions corresponding to the first and second positions respectively of the contact button. A bias means as provided for biasing the contact button to the first position. A crystal vibrator is coupled through first and second coupling members to the first lever arm, the vibration of one of the coupling members causing one of the two coupling members to be displaced, to in turn displace the first lever arm to its second position to selectively control the switching of the switch.
