Abstract
Disclosed embodiments relate to a socket. A speed-control switch, including: a housing including a top plate provided with a central opening extending in a length direction; a push rod at least partially contained in the housing, and a first end of the push rod protruding out of the housing from the central opening and capable of sliding in the central opening; a plurality of connection terminals provided in pairs in the housing and configured to: selectively engage with a second end of the push rod opposite to the first end to limit a plurality of speed indications of the speed-control switch; and a speed selection assembly with a part thereof set on the top plate and configured to allow a selection for a plurality of speed indications of the speed-control switch as the push rod slides in the central opening. The speed-control switch achieve speed switching with a small force. The speed-control switch is suitable for high-power electrical appliances, requires a small number of components, reducing manufacturing costs and assembly time and assembly difficulty.
