Static Bypass Switch parts diagram: 1 thyristor module, 2 backfeed contactor, 3 maintenance bypass switch, 4 snubber network, 5 connector. 10 parts in 5 top-level items. — Static Bypass Switch parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.

#	Part	Qty	What it does
1	Thyristor Module	3×	SCR pair per phase
2	Backfeed Contactor	1×	Contactor that opens the bypass path to prevent energizing a dead mains feed (IEC 62040-1).
3	Maintenance Bypass Switch	1×	Manual make-before-break switch that wraps the UPS for service without dropping the load.
4	Snubber Network	3×	RC network that limits dv/dt across the thyristors.
5	Connector	2×	Mating plug-and-socket pair that joins two lengths of wiring or a cable to a board so a circuit can be assembled, serviced, and separated without soldering.
