Push buttons, pilot devices and signalling equipment from ABB, Schneider Electric and Siemens make up the operator side of a control panel. The range holds over 1,400 products in Harmony, SIRIUS ACT 3SU1, 3SB6, 3SE and 8WD4 series, with contact ratings from 0.2 A up to 16 A. Stoklink ships worldwide from Turkey and quotes project volumes on request.
What's in this range
How to choose
- Mounting hole size: 16 mm, 22 mm and 30 mm are the common cut-outs, and heads, blocks and legends must share the same size.
- Contact configuration: count the normally open (NO) and normally closed (NC) contacts the circuit needs, for example 1NO+1NC.
- Control voltage: match LED blocks and lamps to 24 V AC/DC or the mains control voltage in the panel.
- Series compatibility: operators and blocks from one series, such as Harmony XB4 or XB5, usually fit only within that series.
- Safety function: emergency stop and interlock duties need devices built for them, not general-purpose buttons.
FAQ
Can I mix Schneider Electric heads with Siemens contact blocks?
No. Mounting systems differ between series. Keep the head, contact block and holder within one series, or ask us to confirm a combination before ordering.
What is the difference between a push button and an emergency stop device?
An emergency stop has a red mushroom head and a latching mechanism that holds the contact open until a deliberate release. Standard push buttons are not built for that duty.
Do you ship these parts outside Turkey?
Stoklink ships worldwide from Turkey under EXW terms. Lead time depends on distributor stock, and we quote project quantities on request.
