## Abstract

A controllable switch, a dual-control switch, and a control system including a controllable switch includes a wireless communication module and a switch component. The wireless communication module is coupled to the switch component. The wireless communication module is configured to send a control instruction to the switch component in response to receiving a switching request. The switch component is configured to switch from a first state to a second state after receiving the control instruction. The first state is one of a turning-on state and a turning-off state, and the second state is the other one of the turning-on state and the turning-off state.
