A foot switch includes: a pedal member extending in a front-rear direction; and a base unit connected to the pedal member via a rotating shaft portion. The base unit has: an elastic force applying portion applying an elastic force to the pedal member; a switch portion operated by the pedal member by the pedal member being stepped on and rotating around the rotating shaft portion; and a support portion supporting the pedal member with the elastic force applied from the elastic force applying portion in a state where the pedal member is yet to be stepped on. The elastic force applying portion and the support portion are disposed on one side in the front-rear direction with respect to the rotating shaft portion. The support portion supports a side wall portion of the pedal member.

An insertion device includes a rotor rotating around a first revolution axis, and an assist tool attached to an insertion section with covering the rotor from an outer peripheral side. An assist tool rotates together with the rotor around a second revolution axis when press force is applied from a first protrusion of the rotor to a second protrusion of the assist tool by rotating of the rotor. The first revolution axis of the rotor and the second revolution axis of the assist tool move closer to each other when the rotor and the assist tool are rotating together.

A system and method for enabling a person with very limited motor and verbal skills to communicate with another person. The system has a pair of spring-loaded buttons having a switch and a contact surface that is pushed by the person to send a contact signal to a controller unit to convert the contact signal into an indication signal. The indication signal is sent to an display to display a message in response to the selected movement of the person's head.

A surgical footswitch having elevated auxiliary buttons is provided. In particular embodiments, the surgical footswitch comprises a footswitch base, a treadle mounted on the footswitch base, a first primary button positioned on an upper surface of the footswitch base along a first lateral side of the treadle, a first auxiliary button housing positioned along a lateral side of the first primary button opposite the treadle, and a first auxiliary button mounted on an upper surface of the first auxiliary button housing, wherein an upper surface of the first auxiliary button is elevated in relation to an upper surface of the first primary button.
