The KACON KEX Series Elevator Pushbutton Box is built for elevator inspection, maintenance and emergency control — the control station technicians rely on at the car top and in the shaft. Two enclosure families, KEX-A and KEX-B, take standard Ø22mm control devices in 1 to 5 mounting holes, so each box is configured exactly for its inspection task: up/down travel buttons, emergency stop, mode selector, key switch, indicator lights and, on the B series, a rotary cam switch. Both families carry an IP65 sealed enclosure, a 10A thermal current rating and stable electrical performance in demanding site conditions.
KEX-A — flat-lid enclosures in five sizes (1–5 holes). Cable entry by knock-out, PG13.5 or M16; optional protective guards for the emergency stop position (G versions).
KEX-B — reinforced enclosures with protective ribs around the devices, a hanging eye and an optional KEX-BZ01 mounting guard. The 40T and 50T versions add a rotary cam switch position for inspection/normal mode changeover.

The boxes accept the full KACON Ø22mm device range: flush pushbuttons, illuminated and non-illuminated — including up, down and double-arrow marked buttons for travel control (1NO); indicator lights; selector switches (1NO+1NC); key switches (2NO); two-position pushbuttons; emergency stop switches in small and large mushroom heads, illuminated and non-illuminated (1NC); and rotary cam switches (2NO+2NC or 3NO+3NC) on the B-T models. Protective accessories guard against accidental actuation: the KEG32Y transparent guard and three-prong / four-prong E-stop guards for KEX-A, and the KEX-BZ01 mounting guard for KEX-B.
