XB2-EC Reset Momentary Mushroom Push Button Switch

The XB2-EC Reset Momentary Mushroom Push Button Switch is a modular mushroom head push button switch, available in momentary (non-latching) and self-locking (latching) operation modes, with normally open (NO), normally closed (NC), and NO+NC contact configurations to meet diverse control logic requirements. Its iconic mushroom head design features a large, domed surface that allows for quick activation—even in emergency situations, operators can easily press it with a palm or elbow, ensuring rapid response to avoid potential hazards.

Equipped with a standard 22mm mounting hole, the XB2-EC Reset Momentary Mushroom Push Button Switch enables quick and seamless installation on all types of industrial control panels, reducing installation time and labor costs. Crafted with high-quality flame-retardant PC shell and silver alloy contacts, it is designed to withstand frequent operation in harsh industrial environments, including dust, humidity, and moderate vibration, ensuring long-term reliable performance for critical control systems. The switch is also available in illuminated and non-illuminated versions, with multiple color options to facilitate quick function identification.

Product Feature

1.Ergonomic Mushroom Head Design

The large, domed mushroom head (available in 40mm size option) provides a large contact surface, enabling quick and easy activation even in emergency or high-pressure scenarios. The rounded, smooth surface ensures comfortable operation, reducing operational fatigue during frequent use, while the prominent design makes it easily identifiable on control panels—ideal for emergency stop and quick start applications.

2.Dual Operation Modes

Momentary mode (non-latching) resets automatically after the button is released, ideal for temporary control scenarios such as emergency stop, start signals, and momentary signal input. Self-locking mode (latching) maintains its state after being pressed, ensuring stable equipment operation without continuous manual operation, suitable for long-term status control and mode switching.

3. Modular & Flexible Configuration

The series features a modular structure, consisting of contact modules, base, and mushroom head, connected by a fastener-free self-locking design for safe, reliable, and easy disassembly—one person can complete the maintenance work. Contact blocks can be easily replaced without disassembling the entire switch, supporting flexible configuration of 1NO, 1NC, and 1NO1NC to meet specific project requirements, enhancing operational flexibility and cost-effectiveness.
