Abstract: A switch in one embodiment includes a knob slidable through an aperture in a bezel. The knob is guided within a post mounted on a carrier and is biased to an outward position with respect to a carrier. A latch movably mounted on the carrier is rotated between two positions by a member carried on the knob on each successive depression of the knob. In one position, a projection on the latch extends through aligned bores in the post and a stem carried on the knob to lock the knob in a second position. Movement of the latch in an opposite direction, on the next depression of the knob, releases the projection from the aligned bores enabling the knob to biasingly move outward to the first position. Preferably, the carrier is rotatable relative to a support. The knob is keyed to the post on the carrier such that when the knob is in the second position, rotation of the knob causes rotation of the carrier. In another embodiment, two pushbuttons are disposed side-by-side for independent and/or simultaneous movement.
