A flexible arm is supported in suspended relation on a holder and includes a support leaf and one or more switch actuating leaves in overlapping relation. The outer ends of these leaves are all secured together but the inner ends of the switch actuating leaves are supported freely on the support leaf. A fulcrum is disposed between the support leaf and a holder therefor and is arranged such that when the support leaf is flexed over such fulcrum, the switch actuating leaves form a lever for actuating a movable switch contact. The connection between the support lead and the support comprises a loop formed in the inner end of the support leaf which encircles and has a telescoping removable fit on a portion of the support. The flexible arm can also move away from the fulcrum to engage and move the switch contact.
