ABSTRACT:
An indicating button 10 for a push-push actuated device 11 (e.g., a switch) is mountable on the device's plunger 20 which controls the "on" and "off" states of the device. Button 20 comprises a hollow casing 25 in which is rotatably mounted a quasi-spherical indicator 50 having two surface portions 101, 102 of different appearance which are selectively viewable through a plano-convex lens 90 in the top of the casing at different angular positions of the indicator. The indicator is driven to these different positions at "in" and "out" positions of plunger 20 by a resilient crank arm 70 coupling indicator 50 and device 11 and adapted by resilient bending to convert linear "in" and "out" movements of button 10 and plunger 20 into rotary movements of the indicator.
