(1) Miniature snap switches tted with a lever are supplied with the lever xed in position A (see page 46). For basic (plunger) snap switches, it is possible to x the
lever in position A or B, depending on the required tripping conditions (see page 46).
(2) Position of the operator in relation to the switch xings (xing hole centre line) at the instant the switch contact changes state.
