Modular push type latching and cross cancelling switches

摘要

A modular push type latching and cross cancelling switch operated by manual push motions. A pair of displaceable contact carriers (150, 250) are slidably mounted within an enclosure and have multiple positions for making electrical contacts. Rotatable cams (170, 270) are positioned adjacent each contact carrier and via selected camming surfaces control the position of the contact carriers. A pair of cam actuators (130, 230) are displaced by push motions and include contact surfaces for engaging each of the rotatable cams to displace the cam to cause one contact carrier to be placed in the desired "on" or "off" position and to place the other contact carrier in the "off" position if it was in the "on" position.
