ABSTRACT:
The present invention relates to a two position valve having a cam and a cam follower mechanism for holding the valve element in either of its two operative positions, depending on the operation of a push button switch arrangement cooperating with the valve so that the valve shifts between positions in response to pushing the switch. The cam takes the form of an arrowhead shaped groove having first and second apex portions in which the cam follower, a spring loaded pin, traces. The groove is formed with a step at one apex to prevent the pin from reversing its trace and to ensure its oneway tracing about the groove.
