22mm pushbuttons, stocked in Australia.
Where it's specified
Specified by [the trades who use it.]
Panel builders and OEMs order operators and contact blocks as matched sets; maintenance teams order the single operator that failed. Both come off the same shelf.
Also stocked for industrial MRO — the one operator that failed, like for like — and lift, crane & hoist.
From start button to E-stop.
Operators, indication, switching and enclosures — so the whole control side of a job comes off one invoice. Everything below is held in Australian stock.
aafbuc3vxdhowtuhnyaigenblockbec93d3p9qh6m
Non-illuminated flush operators in green, red, black, blue, white and yellow, plus green and red mushroom heads, arrow operators and Start–Stop dual pushbuttons. The workhorse of any start/stop station.
aafbuc3vxdhowtuhnyaigenblockbec93d3p9qh6m
Flush illuminated operators in five colours at 24 V AC/DC, with red and green also at 220 V AC/DC — for start/stop stations where the button also carries the status.
aafbuc3vxdhowtuhnyaigenblockbec93d3p9qh6m
Flat LED indicators in six colours — red, green, amber, blue, white and yellow — at 24 V AC/DC and 220 V AC, with red and green also held at 12 V AC/DC. The widest colour and voltage spread in the range.
aafbuc3vxdhowtuhnyaigenblockbec93d3p9qh6m
Two and three position, maintained or spring return, including left and right spring-return variants for hand–off–auto and jog duty.
aafbuc3vxdhowtuhnyaigenblockbec93d3p9qh6m
Two and three position keyed selectors, including pull-out-in-both and pull-out-in-all-positions variants where the key must not be left in the panel.
aafbuc3vxdhowtuhnyaigenblockbec93d3p9qh6m
40 mm red mushroom emergency stop, twist to release. The LAAWS yellow identification ring is ordered separately. Contact blocks are ordered separately — NC as standard, using LAA01 or LAA02 blocks, with NO blocks available for signalling.
az3dxee8ym2plcmpzraigenblockbec93d3mbtpfi
1NO, 1NC, 1NO+1NC, 2NO and 2NC. AgNi10 contacts, 100,000 cycles on single-contact blocks. Not included with any operator — see below.
az3dxee8ym2plcmpzraigenblockbec93d3mbtpfi
Empty ABS control station boxes, 76 mm wide and 59.6 mm deep, with a Ø20.2 mm cable entry. The single-hole box comes with a yellow or grey cover; the two and three hole boxes are grey, at 50 mm and 35 mm hole spacing.
az3dxee8ym2plcmpzraigenblockbec93d3mbtpfi
Printed STOP and START plates, plus a blank, that mount under the operator, so the station is marked at the button rather than with a label stuck to the panel.

The LA1 series.
Telergon has been manufacturing switching product from Zaragoza, Spain since 1953 and sells in more than 100 countries. The LA1 thermoplastic auxiliary control series is its front-of-panel range — operators, indication, legend plates and contact blocks built to IEC 60947-5-1, CE marked under the Low Voltage and RoHS Directives.
Operators are rated IP65 from the front of the panel, contact blocks use AgNi10 contacts rated for 100,000 operations, and every operator, block and legend plate in the range is interchangeable across the series.
European engineering. Local supply.
Telergon designs its own switching product from Zaragoza, Spain and has done since 1953, selling in more than 100 countries. TROPAC holds the range in Australian stock, with PAC specification support behind it.
