Abstract
A miniature push-button switching apparatus having a housing for enclosing a plunger and a rotating ratchet mechanism for engaging and disengaging the switching contacts, the switching apparatus having a 'momentary-on' position for temporarily engaging an electrical load in addition to a 'stable-on' switch position with the ratchet mechanism employing a helical contact spring as a switching contact, the contact spring increasing the active length of the switching contact for significantly reducing possible spring yielding problems and further exhibiting improved resiliency properties which enhance the ratchet switching mechanism and reduce the possibility of spring distortion.
