Push Buttons and Enclosures

What this family covers

Everything that goes on the front of a panel and everything behind it: 22 mm push buttons, selector switches, emergency stops, pilot lights, the contact and LED blocks that sit behind them, and empty enclosures for building a control station where there is no panel door to use.

The range

• Push buttons — flush, extended and illuminated versions, in metal and chrome series, with custom markings available on request.
• Mushroom buttons — 40 mm heads including emergency-stop and special-function versions.
• Selector switches — maintained, momentary and key-release, in two- and three-position forms, with illuminated versions.
• Pilot lights — indicator lamps in the same 22 mm format.
• Contact and LED blocks — normally open (WL22-BE101) and normally closed (WL22-BE102) blocks that stack behind the operator.
• Push button enclosures — empty thermoplastic boxes with IP54 protection, multiple colours and cable gland options, for compact control stations.

Standards and construction

The range complies with EN 60947-5-1 and EN 60947-5-5, with IP65 protection to EN 60529 on the panel-mounted operators. Bodies are thermoplastic, heat and shock resistant, tested to IEC 60695-2-11 and passing the glow-wire test at 700 °C. Contacts use a silver alloy (Ag/Ni). Fixing ring tightening torque, rigid and flexible wire cross-sections and pre-insulated ferrule sizes are all listed in the catalogue tables.
