REES 40102-104 Yellow Mushroom Push Button Lockable

REES 40102-104 Yellow Mushroom Push Button Lockable is a lockable push-button switch featuring a yellow mushroom-style head and a 2" plunger, built for reliable manual actuation in control panels and equipment enclosures. Its NO-NC configuration indicates it can be wired for normally open or normally closed circuits, while the lockable mechanism lets authorized personnel secure the button in its current state to prevent unintended operation. The 2" plunger travel provides a defined actuation point suitable for panel-mounted interfaces in space-constrained control layouts, helping with consistent operator feedback. The yellow head enhances visibility in busy control environments, and the part is identified by the 40102-104 designation from REES, ensuring precise ordering and replacement within the brand's line of lockable mushroom push buttons. In applications requiring controlled/manual startup or stop actions with tamper resistance, this lockable mushroom push button offers a straightforward, human-friendly interface in a compact form factor.
