To ask: the traditional mechanical relays and solid-state relays have any advantages and disadvantages? Can a solid state relay pass a current of 1 to 2A? Applied to the toy motor is not it?
The traditional mechanical relays, the advantages are: drive simple, good isolation, short-term overload patience is good; drawback is: larger (bulky), slow response (up to ms level), drive the power consumption of the relay. The solid-state relay is just the opposite, small size, responsive (us level), but poor resistance to electrical shock, less isolation (except for optical coupling devices), high current load characteristics deteriorate. With the development of modern electronic technology, solid-state relays to replace the traditional mechanical relay trend is very obvious. Solid state relay according to the load capacity to points, with pressure, rated current, and so the distinction between indicators. You only need to find the voltage, the current can meet your load model of the solid state relay can be (but also to distinguish the load is DC or AC type). Generally solid state relay, large can be done more than 10A. But the capacity up, the price also went up.

The current can be done very large, 1 to 2A certainly no problem.
The cost of using toys may not be cost-effective
