Abstract: A dryer timer includes a housing and a motor and a cam assembly carried in the housing. A switch in the housing is responsive to the cam to switch the motor between a 120 VAC standard timer circuit and a 240 VAC dryer heater circuit. A leadless voltage dropping resistor in the 240 VAC circuit is mounted on the exterior of the housing clasped between the feed-through to the switch and a terminal strap connected to the timer terminal which connects to the dryer heater circuit. A flanged member connected to the feed-through and the terminal strap engaged the flat surfaces of the disk-shaped leadless voltage dropping resistor to dissipate the heat it produces.
