Disclosed herein is a switch construction including a switch support having a protuberance and an electrically nonconducting switch member movable on said support and including a main body and a part extending resiliently from said main body and having an electrically conducting contact biased toward said support and movable, in response to movement of the switch member, between a position of contact with the support when the switch member is in a first position and a position of noncontact with the support when the switch member is in a second position. The part also has a foot which is biased toward the support and which is movable, in response to movement of the switch member, between a position out of engagement with the support when the switch member is in the first position and a position of engagement with the support when the switch member is in the second position. In one embodiment, the foot moves relative to the protuberance to provide an impositive detent for both first and second switch positions. In another embodiment, the foot moves relative to the protuberance to cooperate in establishing engagement between the contact and the support and to provide an impositive detent for at least one switch position.
