Siemens 3SB36 03-0BB61 Pushbutton With Contact Block

Siemens 3SB36 03-0BB61 Pushbutton With Contact Block is a 22 mm round, plastic pushbutton from the SIRIUS 3SB3 family, offered as a complete device with an integrated contact block (03-0BB61) for front‑panel mounting. The actuator is a raised button with a concave operating surface, and the actuator diameter is Ø22.3 mm, designed to sit on standard 22 mm DIN panels. This 3SB36 complete device supports Siemens’ modular contact‑block approach, allowing a variety of configurations on a single panel: the same family can accept multiple contact blocks and lampholders depending on the selected option; the layout is compatible with configurations that use up to three contact blocks or two contact blocks plus a lampholder, as described in Siemens 3SB3 documentation. Electrical ratings for the 3SB3 family place the devices at up to 300 V AC with a typical 10 A per contact block, suitable for control‑circuit switching and interface tasks. The 3SB36 variant is designed for front‑plate mounting with standard mounting options such as screw‑terminal or spring‑terminal contact blocks, and is compatible with the 22 mm front‑plate ecosystem used across Siemens automation panels, making it well suited for signaling and user‑input functions such as start/stop, reset, or selector‑type operations on compact control panels.
