Timer and Electrical System parts diagram: 1 exposure timer, 2 relay, 3 lamp transformer, 4 power cord, 5 connector, 6 wire bundle. 7 parts in 6 top-level items. — Timer and Electrical System 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	Exposure Timer	1×	Electronic timer switching the lamp circuit with 0.1 s resolution, with a focus override that holds the lamp on.
2	Relay	1×	Lamp switching relay
3	Lamp Transformer	1×	12 V halogen supply
4	Power Cord	1×	Mains lead routed through the timer so the lamp only lights during exposure or focus.
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.
6	Wire Bundle	1×	Group of insulated conductors cut to length, terminated, and bound together to carry power and signals between the assemblies of a machine.
