ABSTRACT:
A touch button switch includes a body (10) having a conductive actuator (28) slidable from one end against a surface (62) to actuate a switch (61) on a board (52) which is held in place by hook latches (53) engaging mortises (55) in the circuit board. The surface (62) may provide conduction from the touch pad to electronic motionless switch circuitry (66) so that the touch button is usable either as a tactile switch touch button, as a motionless touch button, or both. Or, the actuator can be blocked from sliding by means of a spacer (68); and the switch (61) may be replaced by a structure (61a) holding an electrically conductive surface (62a), or not: either way, the touch button will then operate only as a motionless touch button. Or, the surface (62) can be disconnected (65) from the circuit (66), or the circuit (66) can be not installed, to operate only as a tactile switch touch button.
