Abstract
An electrical switch arrangement includes a validation switch and four selection switches, all operated by an actuator (31) that can be pivoted about two horizontal axes and can be depressed. A dome center tripper (28) that can be depressed to operate the validation switch has a periphery engaged with an outer contact (44). The actuator has four feet (88) spaced in different horizontal directions from a vertical axis (33). A selection tripper (72) lying on top of the center tripper, has four branches (78) that each lies under one of the actuator feet. When the actuator is tilted, one of the feet depresses one of the branches against one of four selection contacts (56) to close a corresponding selection switch. When a selection switch is closed, current flows from the corresponding selection contact (56) through the selection tripper (72) and center tripper (28), to the outer contact (44), so only a single tail (58) (to be soldered to a circuit board) is required for each selection switch.
