A rubbcr tubo nttnchcd to tho lower oittlct, B, of tlic upper chamber, I, of thc rcylntor (Pig. 1) so8 throiigh E ' (Fig. ), rhich is n holc boml in thc wooer bnso of tho switch, and thcnco rims to R sink. Tho top cutlct, T, runs direct into tho bnth.

When thc tcmpcrnturo of tlio bntli is corrcct, thc mercury in A (Fig. ) stands just bclo~v tho cnd of tho wire, R". If thc tcmpcrntnrc riscs tho mcrcury risca nrid touchcs thc cnd of R", thus coniplcting tho circuit, producing tho clcctroningnct, RS, which then nttrncts thc strip of iron, 11 (Fig. ) nnd breaks tholightirigcirciiit nt C, thus removing tho source of heat.
